I submitted an email address change through my account page and received a confirmation link, but I am unable to log in with the new email address.
After requesting an email address change on your account page, you will receive a confirmation link in the new email address's inbox.
Click on the confirmation link sent to the new email address change. If you are already logged in with your previous address, the email change will be successful.
If you aren't logged in already, please enter your previous email address and password to confirm the new email address.
Please note, you cannot change the email address to an existing Heroku account and will receive the error message "E-mail already exists" if attempted.
